Background: Percutaneous nephrolithotomy (PCNL) is the recommended treatment for stones >2 cm in size. The majority of PCNL are still conducted with larger telescopes using tracts up to 30F in size. We have conducted a randomized pilot study comparing mini PCNL with our standard 22F PCNL for renal stones between 10 and 25 mm in diameter.

- Voiding dysfunction is a common issue after prostate biopsies, leading to significant discomfort, and alpha blockers are being considered as a remedy despite mixed evidence.
- A systematic review analyzed data from 808 patients across six randomized controlled trials, focusing on various voiding function measures such as symptom scores and urinary flow rates.
- The results showed that alpha blockers significantly improved urinary outcomes, decreasing symptoms, post-void residuals, and the risk of acute urinary retention after prostate biopsy.
Article Synopsis
- This review aimed to evaluate treatment options for localized prostate cancer in patients who are candidates for or recipients of kidney transplants, following established research protocols.
- The analysis included 60 studies with 525 patients, mostly showing that surgery (78%) was the common treatment approach, along with some patients receiving radiation therapy, while most had low-risk prostate cancer.
- The findings suggest that both surgery and radiation are similarly effective for treating localized prostate cancer in these patients, but emphasize the need for a more extensive multicenter randomized controlled trial for better evidence.
Background: To assess the results of ureterorenoscopy (URS) for upper tract urolithiasis in a contemporary Australian tertiary healthcare setting.
Methods: Hospital records of all URS stone procedures performed between January 2017 and December 2018 in a metropolitan service were retrospectively reviewed. Outcome measures including stone free rates, adherence to postoperative follow-up and complications rates were recorded.
Background: This study aimed to evaluate the compliance and loss-to-follow-up (LTFU) rate in patients with stage 1 testicular germ cell tumours (GCTs) on active surveillance protocol at a metropolitan health service in Melbourne, Australia.
Methods: Patients with stage 1 testicular GCTs diagnosed between 30 June 2012 and 30 June 2018 were identified. Compliance of surveillance programme was classified into three groups: 'adequate', 'missed appointment(s)' or 'LTFU'.
Background: Free-tissue transfer flaps are an effective reconstructive option for complex wounds; however, flap failure is a dreaded complication requiring timely re-exploration and salvage. The aim of this study was to determine whether salvage rates were higher in skin flaps, as opposed to muscle flaps, due to the durability of the overlying skin paddle allowing for better visual post-operative monitoring and more timely recognition of the threatened flap.
Methods: We conducted a retrospective analysis of all patients who underwent a free flap at an Australian tertiary centre between 2004 and 2014.
Delayed diagnosis of an intraperitoneal bladder rupture is rare in the post CT era. We present a case of a middle aged male with a delayed presentation of a traumatic intraperitoneal bladder rupture. He initially presented with an acute distended abdomen and acute kidney injury after an alleged assault.

The aim of this study was to determine the effectiveness of Botox and side-effect profile in the management of CAF.
Methods: A retrospective clinical study of patients between 2010 and 2014 who underwent a Botox injection for CAF at a tertiary centre was performed.
Duodenal perforation by an inferior vena cava filter in a polyarteritis nodosa sufferer.
Int J Surg Case Rep
December 2014
Introduction: Inferior vena cava (IVC) filters are currently used in the management of pulmonary embolism (PE) and lower limb venous thromboembolism (VTE). Despite their widespread use, associated complications including duodenal perforation have been reported.
Presentation Of Case: We describe a unique case of duodenal perforation 2 years post IVC filter insertion in a patient with polyarteritis nodosa (steroid dependent) and thrombocytopenia secondary to chronic cyclophosphamide use.
Background: Aloe vera is a cactus-like perennial succulent belonging to the Liliaceae Family that is commonly grown in tropical climates. Animal studies have suggested that Aloe vera may help accelerate the wound healing process.
Objectives: To determine the effects of Aloe vera-derived products (for example dressings and topical gels) on the healing of acute wounds (for example lacerations, surgical incisions and burns) and chronic wounds (for example infected wounds, arterial and venous ulcers).
